- ancewith the position of the gate, so as to eliminate'shocks and wear upon the various parts of the gate mechanism.

With the aboveA and other objects in View,

' the nature of which will more fully appear i weight housing;

Fig'. 4' is a fragmentary top edge view as the description lproceeds, theinvention consists in the nove construction, combination and arrangementA of parts as yherein fully described,' illustrated and claimed'. In the accompanying drawings, forming part of theapplication, `similar characters of reference Aindicate corresponding parts in all the views. 'l

Figure 1 'is a perspective view of a gate embodying my invention;

Fig. 2 1s a vertical section on line 2,-2, Fig. 1.

Fig. 3 isa vertical section of the main ofthe gate and the post receiving it;

Fig. 5 is a fragmentary enlarged view of the upper end of the gate posts; and

Fig.l 6 is a horizontal section 'on line 6 6, Fig. 4.

Referring to the drawings, 9 is the gate which lis hinged at one ofits lowest corners 10 .to a Vpair of gate posts 11 between which the gate is mounted to tilt on the corner 10. Thev posts 11 rise above the gate in normalv 'position The top of each post carries a pair of uiding sheaves 12 mounted in. a suitable rame 13 lsecured to the post. The gate has preferably a vcentral vertical post 14 to' which one end of a pair of iexible members 15 is secured. Each ofthe fiexible members ass between the sheaves 12- of a correspon ing post 11.. Italso passes over a guiding pulley 16 provided on a suitable A standard 17 substantially on a level with the sheaves 12. VA Weight 18 is carried by each of the fleirible members at the standnat the start.4 weights 18 begin to resist the movement of rthe gateunder lthe mainfweight 21 the flexard 17. The tendency of the two weights 18 is to move the gate on its hinge between the posts 11. The two posts are preferably reinforced on their bases by braces 19.

The corner of the gate above the hingedv corner 10 is connected by a iiexible member 20 to a weight 21 mounted to move within a housing 22 whichis in the shape of a col'- umn erected in the rear of the gate. able guiding pulleys 23 are provided with- Suitin the column for the flexible member. The weight 21 normally carries an additional Weight 24 which becomes detached from the weight 21 by means of shelves orvp'rojections 25 formed within the column in the path of the weight 24 when the weights 21 and 24 are setfinto motion by a displacement of the gate. The said shelves or projections are so located .within the column-22 that the said auxiliary weight 24 loses its effect upon the gate when said gate reaches the position diagonal; that is, approximately at an angle' of 45 the auxiliary weight 24 loses its effect upon the gate 9. It will be noted that at substantially that positionof the gate the weights 18 have lost their effect u on the gate; and the further movement o the gate under the main Weight 21 will be resisted partially by the lweights 18, thereby preventing a rapid movement of the gate t'o its open position under the momentum imparted to it by various weights At the-moment when the ible members 15will come into'contact with the sheaves 12 located near the rear end of tated by the Weights 18 until it reaches an angle of 45". At this point the auxiliary vmovement to the closed position is facilip Weight 24, as Well as the weights`18, will f begin to offer further resistance to the movement of the gate under the. action of gravity. It will be noted'that after 45 the actionfof gravity upon'the weight in- Vcreases cons'derably. Therefore, this additional' resistance prevents la: sudden' fall
